<span>Answer:
For the old car:-
By v = u + at
=>v = 0 + 10a
=>a = v/10 m/s^2
By s = ut + 1/2at^2
=>s = 0 + 1/2 x v/10 x 10 x 10 = 5v
Thus F = ma
=>F = m x v/10 = mv/10
=>P(old) = F x s = mv/10 x 5v = 1/2mv^2 ------------------------(i)
For new car:-
By v = u + at
=>6v = 0 + 10a
=>a = 3/5v
By s = ut + 1/2at^2
=>s = 0 + 1/2 x 3/5v x 10 x 10
=>s = 30v
By F = ma
=>F = m x 3/5v = 3mv/5
Thus P(new) = F x s = 3mv/5 x 30v = 18mv^2 ------------------------------(ii)
=>P(new) : P(old) = 18mv^2 : 1/2mv^2 = 36 : 1</span>
Twain mentions four social classes in the novel starting from the top, we have the wealthy, aristocratic people represented by the Grangerfords. Mr. Grangerford was described as a 'well born' kind of person. There is a middle caste of white people. For instance, on page 15, "Why can't the widow get back her silver snuff-box that was stole? WHy can't Miss Watson fat up?'
The next rung down is a lower class of white people like Huck. The very last consists of African American people like his friend Jim.
